Answer: A) 1.8 km
Step-by-step explanation:
Speed = Total distance (train + platform)/ time
1 min = 60 sec, 5 min = 300 sec
Speed (m/s) = (80 + 70)/300
Speed (m/s) = 150/300 = 1/2
Convert it into km/hr [Multiply by 18/5]
1/2 * 18/5
= 1.8 km/hr
Speed (km/hr) = 1.8 km/ hr
In one hour, the train travels 1.8 km.
Answer: 1.8 km.
Thanks.
